` "HEATER `application `filed March 31, 1928. LSerial No. 266,253.

ihisinvention relates to heatere` oi the eahinet type, and is partieulariy directed to the construction and arrangement ot the ra` dieter or heating` chamber thereof, ier a 5 there eiiioient output of heat.

it is an object oi this invention to provide a heater et this type in which the heat-ing ling troni thehase ot the eabehaniher, en inet to the top thereof is of a lengthened torni to provide greater Wall surface or area tor inereneedheat radiation. l

Another ohjeet is to provide a. heating?,` ehaniher or radiator' i'or a cabinet type heater, vertically disposed in the heater cabinet, a id having angled upward trend across the p: Uh oit air travel from the base of the cahinet to the heat openings at the top thereof, en 4ieiently constriotinn,` the path oi air travel Tor proper eontaet ot the air With the inn mense-d Wall areas oit the radiator or heating,l

ehainher. u i

Another object is to reduce the height oi' wi ie rahinet neeeeeary fora given heat eapaeu ot the cabinet are properly insulated or spaced troni the radiator or heating Chaniher, and in `which the arrangement ot the .he i ehanilier provides for an even owoi radiated air from all parte oi the heater, ihrongil the heat opening at the topthereoit.

Uther ohjeets rel-ate to the general features ot eonftrnetion :lor ease of assembly :in 1nanu- "i'iaetnre, and particularly the formation ot the radiator and .tire chamber unit tor oonvenient ineorliorzition in the heater Cabinet. AFurther ohjeets and advantages Will he more Tully eet ttorth in the description ot the areompan,in?, drawineje, in Whiehf Figure i. is a `general perspective View oi ie improved heater, a portion of the front `li ot the cabinet lacing hrohen away to disthe radiator unit ot the heater. Figure `2 is a sectional View taken verti diy ano eroaenfiee through the heater, dis- 'ngr in detail the construction and arwe ele rangement et th i .tire ohalnher and the radi-v ing ehainher Within the heater exhaust opening for causing the heat travel to he more uniform and unaiteeted by the centrally located flue vent.

Figure i is a sectional View` taken on line it-Ji, Figure 9, illustrating` the i'nountingof the gas burners at the hase of the `tire chaniher, and aise Showing the manner oi' insulatingl the lire ehaniher from the heater side Waile.`

Referring to the drawings, a rectangular heater easing or Cabinet is indicated generally at l. yihis easing,l is open at the top and bottoni for the purpose oi allowing the necessary' air circulation therethrough. The lease ot the easing is provided with an encircling; iron hand 2, and legs 3 are provided at eaeheorner thereof. The top of the easing covered by a Cap 4:, having;l a iiange 5 over- `tire Chamber are formed a unit indieated generally at 7, adapted to he inserted Within the ont-er easingl l. A pair oi side Walls 8 are provided for this unit, and transvereeiy disposed Walis provide the ire ehaniher and the heatiing` ohainher. v

The iil'e ehan'iher 9 is defined hy a vertiealiy dieposed rear Wait i0, spaced away from the rear Wall ot the easing' l, and attor- 'Ward extending angled root il extending to a point intermediate of the heater casing, the iront Wall of the easing; l providing the forward wail ofi: the lire Chamber and the side Walis 8 of the unit providing the end Walis oi the tire Chandler, and the har-5e open 'for the noot ary draft.

fi'arailel Walls 12 entend upwardly at a reverse. angle resiieetively 'from the termination of the roof il and the forward Wall ot' the easing' l. rihese Walls Continue upward in zigzag; formation to a point adjacent the top and rear portion ot the casino; l. The transversely paraliel extending Weils i2, are seeured to the side Wails S hy means of turned iiangf'jes i3, riveted or spot Welded to the side wail,

`The chamber or rectangular heat tube llornied by the parallel walls is ot Windingformation or may he said to have an angled upward trend. A vertically disposed wall 14, closes off the upper end of this zig- Vzag radiator. Centrally ofthe vertically wall 'Cil 14;, a flue snout 15, is secured thereto, by means of'bolts 16. The wall 14 is spaced away from theirear ofthe casing 1, and

vz the snout 15, extends Vacross this space and protrudesfrom the rear of thecasing.

A window 16 is provided on the front wall Vof the fire chamber for observing the condition of thefire. Gas burners 17 traverse the lower portionl of `theire chamber and are Y secured at one endby insertion through the strap'ironQ, and at the other end by means 'of screws 18 passing through an end wall of the tire chamber and axially entering caps at ythe ends of the burners.,A Valves 19 are provided at the intake end of the burners for controlling the' flow-ofv gas thereinto, from the main feed line 20. A fuel grate basket 21 .ishung over the burners by attachment to the endwalls Vof thelire chamber.

The fuel basket provides an even flame all through the tire chamber. Y

fA'batlle plate/22 is mountedbetween the end walls 8*, parallel with and spaced slightly awavfrom the roof of the lire chamber. This f battle plate 1s ofheavy construction forprothe heating unit for insulating the casing side walls from `the radiator walls. Apertures 25 connect `the space betweenA the transversely extending walls 1-2 and the front casing walls 1 with the insulating spaces atthe respective side walls of the casing.

The 'cold air intake for the heater is through the open base end thereof, thev air iowing Y upwardly through-the before mentioned connected spaces to v,the top ofthe casing and vduring the courseofits travel therefrom being subjected to Contact with the walls of the radiator. In order to provide that there will be-no'constriction of air travel from the base to thetop of the casing the zigzag radiator is ofrgeneral narrower width at the top than at the lower end thereof.

\ Since the exhaust vent or snout 15, is disposed centrally of the upper end of the radiator or heat tube, the tendency of the products of combustion would be to travel through the zigzag radiator in the form of a cone to this centrally disposed opening. In order to provide that the heat iiow through this radiator will be in parallel lines and consequently evenly distributed, a battle 26 is inserted across the upper end of the radiator, parallel to the rear wall 14 and slightly spaced away from that wall within the radiator, this baille stopping short ofthe walls 8 for providing the end passageways 27.

This arrangement of the radiator walls produces a greater amount of heat from a given source and the heater is much more compact than the conventional type.

' Having described my invention, l claim:

1. A heater construction, comprising, a. rectangular cabinet casing open at the top and bottom for air circulation therethrough, an inner casing mounted within said rectangular casing, said inner casing comprising Vside plates, said side plates being spaced from the end walls of the outer casing and transversely extending walls between said side plates providing a large fire chamber at the base ofthe casing and a zigzag heating' chamber extending upwardly from the lire chamber to anuppcr corner of the heater, means for exhausting the fumes from said heating chamberand said side plat-es ai'icrtured to connect the spaces between the end plates and the end walls of the cabinet casing with the spaces at each side of the heating chamber.

2. In combination with a casing open at the top and bottom, a heater unit for insertion in said casing, said heater unit, comprising, end plates having outwardly turned Vflanges along their side edges, spaced walls secured transversely between said plates, said walls constituting a lire chamber at the lower end and a zigzag heating chan'lber extending upwardly therefrom, means for exhausting the fumes from said heating chamber, and said plates having apertures through those portions `thereof not constituting the heating chamber end walls.

In witness whereof, I hereunto subscribe my name.
